Abstract

The utility model relates to a wire connecting terminal. One end of the utility model is a round wire connecting tube, and the other end is flat and is provided with a contact plane with round holes used for arranging and fastening bolts. The utility model is characterized in that the upper part of the wire connecting tube is provided with screw holes which are provided with screws, and the inner part of the wire connecting tube is provided with an arc pad. When the utility model is used, the wire or the cable with the diameter smaller than the diameter of the wire connecting tube is inserted into the tube, and the screws are fastened, and the pad is oppressed to tightly clamp a conducting wire. The utility model has the advantages that the operation is convenient, the wire connecting terminal can be dismounted and reused, the range of the requirement of the matching size of the wire connecting terminal and the cross section of the conducting wire are wide, and the requirement of the manufacturing material is not high.

Description

Connector

The utility model relates to supply line's conductor jointer tool, is specially a kind of binding post.

At present, the binding post that often uses in China supply line is compression-type, and its version is that an end is circular wire barrel, and the other end is one flat, has on it contact plane that fastening bolt is used circular hole is installed.When lead is connected with it, earlier conductor wire end is inserted in the wire barrel, made its distortion by special-purpose crimp and Press Plier compression wire barrel then, cave inward, lead is clamped.Use this binding post, because deformation takes place when using, the terminal material is had relatively high expectations, as manufacturing with aluminium, this aluminium will reach the aluminium standard No. 1, and will adopt cold-drawn, cold rolling or pressure sintering production; As manufacturing with copper material, this copper material will meet T ₁And T ₂The specification requirement of number copper, and to after making, carry out annealing in process again, otherwise hardness is too high, is difficult to crimping.Another shortcoming of this binding post must be equipped with when just being to use special-purpose Press Plier and with the corresponding crimp of conductor cross-section, when construction is very inconvenient under high-altitude or narrow site condition.Another shortcoming is exactly that this binding post can only disposablely use, and just can not pull down from lead after the crimping again.Last shortcoming is exactly when its caliber size specification of binding post selected and conductor cross-section dimensions mismate, and it is insecure to produce crimping, easily causes fault to powered operation.

The purpose of this utility model is a kind of less demanding, easy to install to making material at the shortcoming design of above-mentioned binding post, can pull down repeated use from lead, requires undemanding binding post with the conductor cross-section fit dimension.

The purpose of this utility model is achieved in that on the basis that does not change above-mentioned compression-type binding post basic configuration structure, offers screw on the top of wire barrel, places screw in the screw, places the liner of an arc in wire barrel.

Through above-mentioned improved binding post, need only during use diameter is inserted in the wire barrel less than lead (or cable) end of wire barrel caliber, the arc liner is covered in lead top, screw in screw, make the screw top suppress liner, thereby lead is clamped between liner and the wire barrel bottom surface, promptly finishes being connected of lead and terminal.Since do not need compression during the wire barrel wiring, therefore not strict to the material requirement of terminal, as long as guarantee its conductance, can manufacture by casting or compacting by general brass or aluminium alloy; Owing to adopt screw pressure to connect, only need to tighten screw during operation and get final product with general wrench, saved heavy crimp tool and mould; If need terminal is pulled down from lead, as long as loosening screw, lead can be extracted out from the terminal connections pipe, and terminal is reusable; Because the clamping of lead is to finish by the extruding of liner, so requiring with the wire barrel caliber is strict, the diameter of lead do not coincide, all can as long as be not more than caliber.

Accompanying drawing is depicted as structural representation of the present utility model.Wherein Fig. 1 is its cutaway view, and Fig. 2 is Fig. 1 vertical view, and Fig. 3 is along Figure 1A-A cutaway view.

In conjunction with Fig. 1 to Fig. 3, removable binding post one end provided by the invention is flat contact plane (1), have two on it for the circular hole (2) that fastening bolt is used is installed, the other end that links to each other with this plane is circular wire barrel (3), its outer wall top is projection (working the effect of gaining in strength) slightly, have two screws (4) on it, should there be two bolts (5) to be screwed into mutually, one arc liner (6) is arranged in the wire barrel, when lead (7) inserts in the wire barrel, liner is placed lead top, and by tighting a bolt, the roof pressure liner clamps lead.

Claims

1, a kind of binding post, the one end is circular wire barrel (3), the other end is the flat contact plane (1) that has construction bolt with circular hole (2) on it, it is characterized in that, said wire barrel top has screw (4), be equipped with screw (5) in this screw, be equipped with the liner (6) of arc in the wire barrel (3).
